--- Comment #1 from Tanu Kaskinen <tanuk at iki.fi> ---
It seems like you have faulty hardware that sends bogus jack events. It would
be good to have an easy way to disable flickering jacks (or maybe we could do
that even fully automatically), but for now disabling a jack requires changes
to the files in /usr/share/pulseaudio/alsa-mixer/paths/. The problem with
editing those files is that the files will be restored every time your
distribution updates the pulseaudio package.

Anyway, if you want to stop PulseAudio from using "Front Headphone Jack", you
can remove all "[Jack Front Headphone]" sections from the files in
/usr/share/pulseaudio/alsa-mixer/paths/. (Maybe take backups first.)

The bug title says that that you don't have module-switch-on-port-available
loaded, but still the output is flickering. What do you mean by that? Does the
sink port in pavucontrol flicker, or does the sink port seem to stay the same,
but you can hear the flickering, or do you only see some log messages?

If module-switch-on-port-available is not loaded, then the sink port shouldn't
flicker in pavucontrol.

If the port stays the same, but you can hear the flickering, that's probably
caused by the alsa driver that does auto-muting. Pulseaudio can't do anything
about that.

If the log messages are the only problem, you should be able to get rid of
those if you edit the path files as described above.
